Morningstar TriStar TM

Three-Function Solar Controller

The Morningstar TriStar Controller is a three-function controller that provides reliable solar battery charging, load control or diversion regulation. This controller operates in only one of these modes at a time but two or more controllers may be used to provide multiple functions.
The Morningstar TriStar uses advanced technology and automated production to provide exciting new features at a competitive cost. The controller is UL listed and is designed for both solar home systems and professional applications.

Standard Features:

  • Ratings are actual to 50°C and meet UL requirements; no need to de-rate
  • Choice of 7 different regulation or LVD setpoints selectable via DIP switches; eliminates troublesome rotary switches and “trim pots”
  • RS-232 comm port provides for a wide range of custom setpoints
    • DB-9 connector, 9600 baud
    • Designed for PCs and “Palm Pilots”
    • May be used for:
      • adjusting control setpoints and parameters
      • data logging with 30 days storage (future capability)
      •  remote monitoring and control (future capability)
  •  Self-test runs continuously. If a fault is detected, the fault will be displayed on the digital meter and indicated  with the LED’s
  • Push button will reset from an error or fault, start or stop battery equalization (charge controller mode) or override LVD (load controller mode)
  • 100% solid state for high reliability in harsh environments
  • Microprocessor control for extended capabilities
  • Conduit-ready enclosure for large wire sizes; provides extra room for wire turns
  • Very low voltage drops
  • 5 year warranty
  • Estimated 15 year life

Load Control Mode:

  • Electronic short circuit and overload protection with automatic reconnect
  • Starts all loads including inductive (meters, pumps) with no damage to controller
  • Allows inrush current to 300A
  • LVD has 4 minute delay to avoid incorrect disconnect
  • LED and meter indicates LVD warning and disconnect
  • LVD is current compensated to avoid false disconnect
  • Load protected by an automatic high voltage disconnect
  • Load protected from solar voltage spikes when the battery is removed

Digital Meter Option:

  • Voltage accuracy is 0.2%
  • Current accuracy is 1.0%
  • Meter may be mounted to the controller by removing the controller cover plate
  • 2 x 16 display with backlighting
  • Installs to controller with RJ-11 connector for simple installation
  • Includes 4 pushbuttons for easy “up/down” and “left/right” scrolling
  • Displays self-test results, system information and controller setpoints
  • Remote digital meter for mounting away from the controller (in another room):
    • Flush mount in a wall or fit into a double-gang electrical box
    • Installs with RJ-11 connector
    • Available with a 30 meter cable

Mechanical Specifications:

  • Dimensions:
    • 10.1H x 4.9W x 2.3D (inches)
    • 25.7H x 12.4W x 5.8D (centimeters)
  • Weight: 4 lbs (1.8 kg)
  • Wire Terminals:
    • Sized for up to 2 AWG (35 mm2)
    • Torque to 50 in-lb
    • Positive terminals are separated from negative terminals
  • Conduit Knockouts:
    • Eccentric 1”/1.25” (2.5/3.2 cm)
    • Located bottom, sides and back
  • Enclosure:
    • White powder-coated steel
    • Indoor rated, vertical mounting
  • Heat sink: Black electrolytic anodized aluminum

 Electronic Protections:

  • Reverse polarity protection (any combination)
  • Solar and load short circuit protection
  • All other connectors are short circuit protection
  • Solar and load overcurrent protection
  • Lightning and transient surge protection using 4500W transient voltage suppressors
  • High temperature protection via automatic current reduction or complete shut-down

Charge Controller Mode:

  • Constant voltage series PWM to provide highly efficient battery charging
  • 4 stage charging to increase battery capacity and life: bulk charge, PWM regulation, float and equalize
  • 3 LED’s indicate battery state-of-charge, controller status and battery service required
  • Parallel for larger solar arrays up to 300A or more
  • PWM may be changed to “on-off” controller to minimize any possible telecom noise
  • Temperature compensation via optional remote temperature sensor
  • Battery sense connector to eliminate voltage drops between the controller and the battery

Diversion Control Mode:

  • May be used for solar, wind or hydroelectric
  • To protect against battery overcharge, excess energy is diverted from primary battery to a secondary battery or alternate DC resistive load

Remote Temperature Sensor Option:


  • Accurately measures temperature at the battery and compensates regulation setpoints
  • Cable length is 10 meters; may be increased to 30 meters
  • Rated from -30°C to +80°C
  • Defaults to 25°C if temperature sensor reading is out of range or fails

Environmental Specifications:

Operating ambient temperature: – 40°C to +50°C; For 60°C, de-rate 20%
Storage temperature: -55°C to +85°C
Digital Meter operating temperature: -30°C to +85°C
Humidity: 100% (non-condensing)

  • Conformal coating on both sides of all printed circuit boards
  • Electrolytic anodized aluminum heat sink
  • Powder-coated steel enclosure
  • Stainless steel fasteners
